Please explain the relationship between between functions, classes and objects in C++. Analogies really help me learn. If you could provide some example code that would be phenomenal.

What I have so far is that a class is like a template, it defines the names of the attributes but doesnt give them values. Object from class gives values to attributes. Like the Class Corolla will say that the car has doors, a license plate, and a color. The object from the class will give value to its attributes. In example, the Corolla is a four-door, with a license plate of so-and so, and it's blue. I have no idea how this relates to the function and if you could explain it with the car analogy that would be swell.... and provide some simple code to demonstrate.
